context_page_description: Reggio nell'Emilia, usually referred to as Reggio Emilia or colloquially Reggio by its inhabitants, is a city in northern Italy, in the Emilia-Romagna region. It has about 171,944 inhabitants and is the main comune of the Province of Reggio Emilia.
  The inhabitants of Reggio nell'Emilia are called Reggiani, while the inhabitants of Reggio di Calabria, in the southwest of the country, are called Reggini.
  The old town has a hexagonal form, which derives from the ancient walls, and the main buildings are from the 16th–17th centuries. The commune's territory lies entirely on a plain, crossed by the Crostolo stream.
context_section_description: Reggio became a free commune around the end of the 11th or the beginning of the 12th century. In 1167 it was a member of the Lombard League and took part in the Battle of Legnano. In 1183 the city signed the Treaty of Konstanz, from which the city's consul, Rolando della Carità, received the imperial investiture. The subsequent peace spurred a period of prosperity: Reggio adopted new statutes, had a mint, schools with celebrated masters, and developed its trades and arts. It also increasingly subjugated the castles of the neighbouring areas. At this time the Crostolo stream was deviated westwards, to gain space for the city. The former course of the stream was turned into an avenue called Corso della Ghiara (gravel), nowadays Corso Garibaldi.
  The 12th and 13th century, however, were also a period of violent internal struggle between the Scopazzati (meaning "swept away from the city with brooms", nobles) and Mazzaperlini (meaning "lice killers", plebeians) parties, and later those of Ruggeri and Malaguzzi, involved in a bitter domestic rivalry. In 1152 Reggio also warred with Parma and in 1225 with Modena, as part of the general struggle between the Guelphs and Ghibellines. In 1260 25,000 penitents, led by a Perugine hermit, entered the city, and this event calmed the situation for a while, spurring a momentous flourishing of religious fervour. But disputes soon resurfaced, and as early as 1265 the Ghibellines killed the Guelph's leader, Caco da Reggio, and gained preeminence. Arguments with the Bishop continued and two new parties formed, the Inferiori and Superiori. Final victory went to the latter.
   
  To thwart the abuses of powerful families such as the Sessi, Fogliani and Canossa, the Senate of Reggio gave the city's rule for a period of three years to Obizzo II d'Este. This choice marked the future path of Reggio under the seignory of the latter's family, as Obizzo continued to rule de facto after his mandate has ceased. His son Azzo was expelled by the Reggiani in 1306, creating a republic ruled by 800 common people. In 1310 the Emperor Henry VII imposed Marquis Spinetto Malaspina as vicar, but he was soon driven out. The republic ended in 1326 when Cardinal Bertrando del Poggetto annexed Reggio to the Papal States.
  The city was subsequently under the suzerainty of John of Bohemia, Nicolò Fogliani and Mastino I della Scala, who in 1336 gave it to Luigi Gonzaga. Gonzaga built a citadel in the St. Nazario quarter, and destroyed 144 houses. In 1356 the Milanese Visconti, helped by 2,000 exiled Reggiani, captured the city, starting an unsettled period of powersharing with the Gonzaga. In the end the latter sold Reggio to the Visconti for 5,000 ducats. In 1405 Ottobono Terzi of Parma seized Reggio, but was killed by Michele Attendolo, who handed the city over to Nicolò III d'Este, who therefore became seignor of Reggio. The city, however, maintained a relevant autonomy, with laws and coinage of its own. Niccolò was succeeded by his illegitimate son Lionello, and, from 1450, by Borso d'Este.
